They are only loud from behind. The sound wave does not go off the front of the FOB. I have been shooting them for about 6 years now and really like them. Sometimes I shoot an arrow with vanes and it always take me by surprise watching it fly to the target with no FOB on it. You can reuse them on any arrow they fit on and no glue or stripping required. On a pass through shot you will find the FOB and nock right where it was popped off the shaft.

Shot them for years. Got my only bow kill with a FOB. It was cool to see it pop off when it went through the deer. Never did find the arrow though.
I have switched to blazers since but I can't say which is better.

Yes, I have spoke with Paul a couple times. Tremendously knowledgeable fellow. His product is along a totally different train of thought too. I like it and his more than generous technical help he shared with me.
